Reviews of OEM Jeep alternator

I'm now over 9k, and the dealer is saying the alternator is shot. This Gladiator is bone stock with the exception of cosmetic additions. Lame.

upon arriving at the dealer for the test drive, it wouldn\u2019t crank.. they said the alternator went bad.

Maybe examine the old alternator, see if you and a multimeter can determine why it failed. I went to the autostore to replace the alternator on my Jeep, $219! I took mine apart, did a few simple checks and found the problem was just dirt in the brushes. I fixed it with a toothbrush!
